DNA flow-cytometric, histological and hormonal analysis of sertoli cell only syndrome (SECOS).

Sertoli cell only syndrome (SECOS) was identified on histology in 21 cases (16,28%) among 129 testicular biopsies performed in our department for azoospermia over the last 5 years. In these patients history, clinical features, hormonal levels, and histological findings were analyzed. In addition DNA flow-cytometric analysis was performed and showed an almost complete absence of haploid cells. All patients presented with elevated serum FSH levels suggesting a Sertoli cell damage or reduced production of inhibin due to the absence of sermatogenic cells. An good correlation was found between histological findings and DNA histograms. In conclusion SECOS is a syndrome of unknown aetiology presenting in men with azoospermia. DNA flow-cytometric analysis is a reliable, rapid and easy method in the diagnosis of SECOS, and can replace histological examination.

Tuberculosis of the prostate.

We present five cases of tuberculous prostatitis. In all cases this was an incidental histologic finding after transurethral prostatectomy. The patients were all treated with an antituberculous drug regimen. A literature review of this rare condition is included.

Rupture of an aortic anastomotic aneurysm into a ureter.

A case of rupture of a false aneurysm of the distal aorta into the left ureter is reported. The patient presented with purulent hydronephrosis and hematuria. A left aorto-femoral graft had been inserted 3 years earlier, which became infected and was then removed. After 2 years a false distal aortic aneurysm developed, and in the last 6 months recurrent episodes of hematuria have occurred. An aorto-ureteric fistula was confirmed at surgery, and a left nephrostomy was performed with proximal and distal ligation of the ureter and then aneurysmectomy followed by aorto-bifemoral bypass.

Extracorporeal shock wave lithotripsy for lower pole calculi: our experience.

INTRODUCTION: This study was performed in order to evaluate the immediate and long-term outcome of patients undergoing extracorporeal shock wave lithotripsy (ESWL) for isolated lower pole calculi. METHODS: Three hundred and seventy renal units of 350 patients (240 men and 110 women; mean age 55 years) with isolated lower pole renal stones of smaller than 2 cm2 were studied. Follow up ranged from 1 to 52 months (mean, 15 months) to time of censorship, significant period of secondary urologic evaluation. RESULTS: Out of 370 renal units in 350 patients, 212 (57, 29%) were stone-free 1 month after ESWL and 21 (5.67%) spontaneously became stone-free within another 1-52 months (mean, 15 months). Intervention was required after 1-52 months (mean, 17.5 months) and accomplished by ESWL alone (30/350 patients 8.57%) or combined with retrograde endoscopy (10/350 patients 2.85%) while retrograde manipulation was necessary in two of the 350 patients (0.57%). CONCLUSION: Extracorporeal shock wave lithotripsy is the initial treatment of choice in patients with lower pole stones < 2 cm2, because the overall stone-free rate is acceptable and because even in the residual calculi, the risk of suffering symptomatic episodes requiring secondary intervention is low.
